While Gizelle Bryant and Karen Huger were clearly over-the-top characters… only Ashley Darby and Katie Rost were truly enjoyable during RHOP's first outing, which is why we're confused that it's one of their pair getting fired.

So which of the show's youngest two castmates is moving out of Potomac??

For starters, Katie Rost showed up to the taping WITHOUT the huge rock she practically forced Andrew Martin into giving her during last week's finale! (Luckily for the mother-of-three, however, they have since made up and are currently engaged.)

Elsewhere, Ashley Darby continued to be the classiest of the bunch despite being the youngest of the cast, much to the chagrin of Charrisse Jackson-Jordan, Karen Heuger, and Gizelle Bryant.

But things really came to a head when Katie and Robyn Dixon got into an argument about each other's skin color… to the point where one of them actually called for security!

Ch-ch-check out the biggest blow-up from Part 1 of the RHOP reunion (below)!!!
